Abstract

"PARTÍCULAS DE RESINA TERMOPLÁSTICAS, RECIPIENTE DE ESPUMA, ARTIGO MOLDADO, COMPOSIÇÃO DE REVESTIMENTO, E, MÉTODO PARA MELHORAR A RESISTÊNCIA A VAZAMENTO DE UM RECIPIENTE DE ESPUMA FEITO COM AS PARTÍCULAS DE RESINA TERMOPLÁSTICAS EXPANSÍVEIS". Partículas termoplásticas expansíveis ou pré-expandidas, por exemplo partículas de poliestireno, usadas para formar recipientes de espuma. por exemplo copos, tigelas, são revestidas com uma composição de revestimento compreendendo uma parte líquida consistindo de a) polietileno glicol líquido tendo um peso molecular médio variando de 200 a 800, e a parte sólida compreende componentes selecionados do grupo consistindo de: b) cera de poliolefina, por exemplo cera de polietileno, c) um sal de metal de ácidos graxos superiores, por exemplo estearato de zinco ou estearato de cálcio; d) polietileno glicol tendo um peso molecular médio variando de 900 a 10.000; e e) uma bisamida graxa ou amida graxa, por exemplo bisestearamida de etileno, e combinações de b) até e). A composição de revestimento evita ou resiste a vazamento de líquidos e comidas com componentes oleosos e/ou gordurosos e melhora a resistência de aro e as propriedades de ATF dos recipientes de espuma."THERMOPLATIC RESIN PARTICLES, FOAM CONTAINER, MOLDED ARTICLE, COATING COMPOSITION, AND, METHOD FOR IMPROVING LEAK RESISTANCE OF A FOAM CONTAINER MADE WITH EXPANDABLE THERMOPLATIC RESIN PARTICLES". Expandable or pre-expanded thermoplastic particles, for example polystyrene particles, used to form foam containers. e.g. cups, bowls, are coated with a coating composition comprising a liquid part consisting of a) liquid polyethylene glycol having an average molecular weight ranging from 200 to 800, and the solid part comprising components selected from the group consisting of: b) wax of polyolefin, for example polyethylene wax, c) a metal salt of higher fatty acids, for example zinc stearate or calcium stearate; d) polyethylene glycol having an average molecular weight ranging from 900 to 10,000; and e) a fatty bisamide or fatty amide, for example ethylene bisstearamide, and combinations of b) to e). The coating composition prevents or resists leakage of liquids and foods with oily and/or greasy components and improves the rim strength and ATF properties of foam containers.
